add to base16 collection about vim-moonfly-colors

hi @bluz71 thanks for taking the time to explain pour position!

Hello,

Looking at the base16 project and their philosophy I don't believe moonfly is an appropriate theme to add to that collection.

Whilst it is true that moonfly currently fits within the 16 color guideline, that is a limit that could well change as time goes by.

moonfly defined 16 colors and used a bunch more from the xterm-256color palette primarily because I was a long-term Xterm user (not a true-color terminal) which meant I created a Vim cterm theme in parallel to the gui theme. Over the past couple years I ditched Xterm for modern true-color terminals and more recently I have switched over to using termguicolors which means I no use the moonfly cterm theme at all (but it still remains as part of this Vim theme for compatibility reasons).

My other nightfly theme is a GUI-only theme which uses more than 16 colors.

Eventually I could envisage doing the same here with moonfly, maybe in 2 or 3 years, that being to ditch cterm theme entirely and expanding the color palette beyond 16 colors + a few xterm-256colors. Maybe, maybe not. I want the freedom to move beyond 16 colors if that is how this theme evolves.

A bit long-winded, but philosophically moonfly really is not a base16 theme, hence it should not be part of that collection.

Best regards.
